BQ27750: compatibililty of hardware version A1 and A2

Part Number: BQ27750

Hi,

I have a question to the BQ27750. There are different hardware versions available:

1) BQ27750:
     a. DeviceNumber: 0x1750
     b. HW_Version: 0xA2
     c. FW_Version: 0x0004
     d. FW_Build: 0x000c

2) BQ27750:
     a. DeviceNumber: 0x1750
     b. HW_Version: 0xA1
     c. FW_Version: 0x0004
     d. FW_Build: 0x000c

I.     What is the difference between those versions?

II.   Are they compatible (hardware, layout, firmware)? 

III. Can I replace an A1 with an A2 and vice versa?

Thanks for your response,

best regards,

Simon
